A total of 1,036 Chinese eighth graders answered an English proficiency test and questionnaires assessing motivational beliefs. Structural equation modelling results with bootstrapping procedures revealed that intrinsic value can directly and indirectly influence foreign language proficiency via partial mediation effect of self-efficacy while extrinsic value can only directly influence foreign language proficiency with a small magnitude. Moreover, there is no gender difference in the mediation model. Our findings suggested that intrinsic value can help students improve foreign language proficiency by improving their self-efficacy beliefs. The findings contribute to the documents of self-determination theory and hold substantive theoretical and practical implications for foreign language teachers.展开更多

Satisfactory agreement with the general features of the experimental data of pion elastic scattering on the neighboring 4N-type nuclei is obtained without any free parameters. Compared with the experimental angular distributions of pion elastic scattering on ^12 C, ^16O, ^24Mg, and ^28Si nuclei, the diffractive patterns and the positions of the dips and peaks in the angular distributions of ^π-^20Ne elastic scattering are reasonably predicted by the calculations.展开更多
